Wave Storm Reference BNC Cables and the Chord Dave I have heard many cables I have liked over the years, and have endorsed several of them throughout my time writing for Positive Feedback. However, I would never have called any of them essential. My recommendations were always wrapped within circumstances; if you have a system... Read More »

Finally! Bluetooth IEM monitors that present real music in real space without wires! Grado has done it and I am mightily impressed. Surpassing the performance of all other Bluetooth IEMs I have heard or auditioned, the new awesome GT220 Headphones are more authoritative, realistic, smoother, offer a more extended top and bottom end, and present...

Ballads is considered by many as an essential addition to any John Coltrane collection. First released on the Impulse label in mono and then later in stereo, it has continued to cause both consternation and praise by both critics and fans. This new 33 RPM stereo reissue is another wonderful addition to the Acoustic Sounds... Read More »

It is hard to imagine any human inhabitant of planet Earth whose life has not been negatively impacted by the current Covid-19 pandemic. However, amidst this dark cloud there are a few silver linings. One of them is the way it has impacted the listening habits of audiophiles. The feedback that I have received from... Read More »

I have been looking forward to telling you about the Pass Labs XP-12 line-level preamplifier, as I've found the XP-12 to make for an excellent match to the Pass Labs XA25 Class A stereo amplifier (reviewed HERE), as well the First Watt SIT-3 single-ended stereo amplifier (reviewed HERE), which are my current benchmarks for relatively...

One of the unsung perks of reviewing high-end gear is getting to travel without the discomfort of leaving home. When something new arrives, often even before the piece has settled in, I'll sit down for a taste and get the strong impression that the acoustic is unfamiliar, like maybe I've gone visiting another dude with...

"Holistic." "Quiet." "Transparent." Those words are my attempt to summarize the KECES S3 Preamplifier/S300 Combo: A delightful possibility for those who need a simple solution for a powerful, high fidelity system, with excellent headphone performance. As with the KECES E40 integrated amplifier (HERE), the minimalist nature of the Taiwan-born S3, and S300, fits into the... Read More »

I've had the same Linn LP12 turntable in my system for thirty-six years. Regular maintenance has kept it in tip-top condition. Of course it has had a few different cartridges over that time, but with one exception it is the same now as when I bought it in 1984. That one exception being replacing the... Read More »

These Perfect Song articles have moved beyond my original intent: So, what is a perfect song? In my opinion, a perfect song touches you on many different levels. It goes beyond simply how it sounds into the more ethereal boundaries of how it makes you feel. It is a melding of music, lyrics, vocals, and... Read More »

The more I listen to the recordings created by Brendon Heinst and his team, the more enchanted I become. TRPTK has easily become a favorite music label in this household because of the highly varied and non-traditional repertoire, extraordinarily good artists (whom we may not know by name but are very deserving of our attention),...

High performance audio components have a variety of needs to reach their full potential, and one of the most critical requirements is being fed the cleanest AC current as possible. A typical audio system can sound quite respectable with a direct feed of AC current from the wall, however hobbyists that are striving to cross... Read More »

One of the audiophile "tweaks" most often criticized on the internet and in back-room bull sessions is the use of cable lifters to improve system sound. In fact, other than cables, themselves, which are a perennial source of audiophile controversy, there's hardly anything I can think of that gets more consistently negative commentary, with or...

If you're a baby boomer (OK, Boomer!) or one of their children, you no doubt have a strong familiarity of the works of jazz pianist Vince Guaraldi. Or at least, you know him through osmosis, via his compositions for the many Charlie Brown and Peanuts television specials and movies that have aired almost incessantly since... Read More »

If you believe in RFI—no, let me start over. If you believe in science (since RFI is a measurable phenomenon), most likely you are doing something to address RFI. We have all been advised to get those darn wires off the floor. A dozen companies will be happy to sell you specialized lifts at prices... Read More »
